The air duct 54 is opened inside the device housing 1. The first fan 55 is installed inside the air duct 54. The second fan 57 is embedded at the bottom of the device housing 1.

[0035] The auxiliary adjustment component 6 includes a rotating chamber 61, a rotating shaft 62, a driving motor 64, a driving gear 65, a rotating disk 66 and a dust filter 611. A rotating chamber 61 is opened inside the device housing 1, a rotating shaft 62 is arranged at the central position inside the rotating chamber 61, a driving motor 64 is installed inside the device housing 1, a driving gear 65 is arranged inside the rotating chamber 61, a rotating disk 66 is rotatably arranged inside the rotating chamber 61, and a dust filter 611 is clamped inside the rotating disk 66.

[0036] In this embodiment, a connecting bearing seat 661 is embedded in the central position of the rotating disk 66. The rotating disk 66 is rotatably connected to the rotating shaft 62 through the connecting bearing seat 661. The rotating disk 66 can rotate freely with the rotating shaft 62 as the center. The connecting bearing seat 661 can reduce the friction force when the rotating disk 66 rotates while fixing the position of the rotating disk 66. A cavity 63 is opened inside the device housing 1. The cavity 63 is interconnected with the interior of the rotating cavity 61. The drive motor 64 is installed inside the cavity 63. The cavity 63 can fix the position of the drive motor 64. The input end of the drive motor 64 is electrically connected to the controller body 51 through a wire. The controller body 51 can control the opening and closing of the drive motor 64. The output end of the drive motor 64 is clamped with a motor shaft 641. The drive gear 65 is clamped on the outer side of the motor shaft 641.

[0037] In this embodiment, the outer side of the rotating disk 66 is provided with driving teeth 613, and the driving teeth 613 mesh with the driving gear 65. The driving gear 65 can drive the driving teeth 613 to rotate, and the driving teeth 613 can drive the rotating disk 66 to rotate with the rotating shaft 62 as the center. A through groove 67 is opened through the surface of the rotating disk 66, and two groups of through grooves 67 are provided. The design of the through groove 67 facilitates the conduction of the air inlet 541 and the air outlet 542 at both ends of the air duct 54. A baffle plate 69 is embedded in the rotating disk 66, and two groups of baffle plates 69 are provided.

The mounting grooves 68, through grooves 67 and blocking plates 69 are evenly spaced on the surface of the rotating disk 66. This design allows the rotation of the rotating disk 66 to adjust the states of the air inlet 541 and the air outlet 542 at both ends of the air duct 54.

[0038] In this embodiment, a rotating block 612 is provided on the outside of the dust filter 611, and a limiting groove 6121 is provided inside the rotating disk 66. The rotating block 612 is rotatably connected to the rotating disk 66 through the limiting groove 6121. The limiting groove 6121 allows the rotating block 612 to rotate freely while fixing the position of the rotating disk 66. A notch 6122 is provided on the outer side of the rotating block 612. The rotating block 612 abuts against the dust filter 611 on the side relatively away from the notch 6122. When the notch 6122 on the outer side of the rotating block 612 is relatively away from the side of the mounting groove 68, the rotating block 612 can abut and limit the dust filter 611. When the notch 6122 on the outer side of the rotating block 612 is relatively close to the side of the mounting groove 68, the abutment and limiting effect on the dust filter 611 is released. This design fixes the position of the dust filter 611 and makes it convenient for users to disassemble the dust filter 611.

[0039] In this embodiment, a first positioning sensor 511 is installed inside the rotating chamber 61, and a second positioning sensor 512 is embedded on the surface of the rotating disk 66. Six groups of second positioning sensors 512 are provided with the same specifications. The positions of the six groups of second positioning sensors 512 respectively correspond to the through slot 67, the dust filter 611 and the baffle plate 69. The first positioning sensor 511 matches the second positioning sensor 512. The first positioning sensor 511 and the second positioning sensor 512 are electrically connected to the controller body 51 through wires. The design of the first positioning sensor 511 and the second positioning sensor 512 facilitates the positioning of the through slot 67, the dust filter 611 and the baffle plate 69.

[0040] In the present embodiment, the air duct 54 is in the shape of a gate as a whole. An air inlet 541 is provided at one end of the air duct 54 relatively close to the second fan 57, and an air outlet 542 is provided at one end of the air duct 54 relatively far from the second fan 57. External air can enter the air duct 54 through the air inlet 541, and after flowing through the heat dissipation fins 56 inside the air duct 54, it is discharged to the outside through the air outlet 542. A fixing slot 13 is provided on the lower end surface of the device housing 1, and a bottom cover 11 is installed inside the fixing slot 13 by bolts. The fixing slot 13 facilitates the installation and disassembly of the bottom cover 11. A through hole 12 is provided on the lower end surface of the bottom cover 11. Two groups of through holes 12 are provided with specifications. The air inlet 541 and the air outlet 542 correspond to the through holes 12. Two groups of heat conductive blocks 53 are provided with specifications. Heat conductive fins 56 are provided on the inner side of the heat conductive blocks 53. The heat conductive blocks 53 and the heat conductive fins 56 are The heat conducting block 53 and the heat dissipating fins 56 made of copper alloy have strong heat conduction capability. The heat dissipating fins 56 are located inside the air duct 54. The upper surface of the heat conducting block 53 is cross-coated with thermal conductive silicone grease 531. The heat conducting block 53 is tightly abutted against the chip of the integrated circuit board body 4. The thermal conductive silicone grease 531 can make the heat conducting block 53 and the chip of the integrated circuit board body 4 connected more closely, thereby being more conducive to heat exchange between the heat conducting block 53 and the chip of the integrated circuit board body 4. The first fan 55 is electrically connected to the controller body 51 through a wire, and the second fan 57 is electrically connected to the controller body 51 through a wire. The controller body 51 can control the opening of the first fan 55 and the second fan 57. The first fan 55 can accelerate the air flow inside the air duct 54, and the second fan 57 can accelerate the air flow at the bottom of the device housing 1.

[0041] Working principle:

[0042] When the integrated circuit board body 4 is in standby mode, the chip of the integrated circuit board body 4 does not generate heat. At this time, the controller body 51 detects the temperature inside the device housing 1 through the temperature sensor 52, and controls the drive motor 64 to turn on. The drive motor 64 drives the drive gear 65 to rotate through the motor shaft 641. Since the drive gear 65 and the drive teeth 613 are meshed with each other, the rotation of the drive gear 65 can drive the rotating disk 66 to rotate inside the rotating chamber 61 through the drive teeth 613. While the rotating disk 66 rotates, the positions of the through slot 67, the dust filter 611 and the baffle plate 69 are changed. Until the first positioning sensor 511 is positioned and matched with the second positioning sensor 512 corresponding to the baffle plate 69, the drive motor 64 is automatically turned off, so that the position of the baffle plate 69 when it stops corresponds to the air inlet 541 and the air outlet 542 at both ends of the air duct 54, thereby blocking the air inlet 541 and the air outlet 542, so that the inside of the air duct 54 remains in a cut-off state to prevent dust from entering.

[0043] When the integrated circuit board body 4 works at low power, the chip of the integrated circuit board body 4 generates less heat. The temperature sensor 52 detects the temperature inside the device housing 1 and controls the drive motor 64 to start. The drive motor 64 drives the rotating disk 66 to rotate around the rotating shaft 62 through the drive gear 65 and the drive teeth 613 until the first positioning sensor 511 is positioned and matched with the second positioning sensor 512 corresponding to the dust filter 611. The position of the dust filter 611 when it stops corresponds to the air inlet 541 and the air outlet 542 at both ends of the air duct 54, so that the inside of the air duct 54 is connected to the outside atmosphere, and natural heat dissipation can be performed;

[0044] When the integrated circuit board body 4 works normally, the temperature sensor 52 detects the temperature inside the device housing 1, controls the driving motor 64 to start, and makes the air inlet 541 and the air outlet 542 at both ends of the air duct 54 correspond to the dust filter 611, and controls the first fan 55 to start. The first fan 55 will accelerate the air flow inside the air duct 54, so that the outside air enters the air duct 54 through the dust filter 611 and the air inlet 541, and exchanges heat with the heat dissipation fins 56 when flowing through them, so as to perform standard heat dissipation on the chip of the integrated circuit board body 4;

[0045] When the integrated circuit board body 4 works at a high load, the chip of the integrated circuit board body 4 will generate a large amount of heat, causing the temperature inside the device housing 1 to rise rapidly. At this time, the driving motor 64 is turned on, and the rotating disk 66 is driven to rotate through the driving gear 65 and the driving teeth 613, so that the air inlet 541 and the air outlet 542 finally correspond to the through slot 67. Although the dust filter 611 can prevent the entry of dust, it inevitably has a certain obstruction effect on the air flow. The air inlet 541 and the air outlet 542 correspond to the through slot 67, which can maximize the air flow. At the same time, the first fan 55 and the second fan 57 are turned on at the same time. The first fan 55 accelerates the air flow inside the air duct 54, and the second fan 57 can accelerate the air flow at the bottom of the device housing 1, thereby achieving the maximum heat dissipation effect.

[0046] This device can achieve different heat dissipation functions by changing the position of the rotating disk 66 according to actual usage and heat dissipation requirements to ensure that the device is always used normally with the optimal heat dissipation function. As the usage time increases, when the dust filter 611 needs to be cleaned, the user first opens the bottom cover 11 to expose the rotating cavity 61 and the rotating disk 66 inside, and then rotates the corresponding rotating block 612 so that the side of the rotating block 612 with the notch 6122 on the surface is close to the installation groove 68, thereby releasing the abutment and limiting effect on the dust filter 611, and the dust filter 611 can be removed for cleaning, which is simple and convenient to use.

[0047] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0048] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
